As a central part of a nutrient dense diet, NatureSource® Natural Beef is an excellent way to make every calorie count.

A 3-ounce serving of lean beef contributes less than 10% of the calories in a 2,000-calorie diet. The amino and fatty acids in our corn-fed beef provide a concentrated source of energy and aid nutrient absorption to fuel your fat-burning engines. The iron and niacin slow down food absorption so you can go longer between meals without feeling hungry.
